I'm trying to figure out if my reasoning for eliminating all of the incorrect answer choices is sound. If you have time, or have done the question already, it'd be great to hear how you chose between choices B and E.
I'm going to reiterate other people's points here, that 7Sage is the best way to go. I've done Kaplan and it was pretty bad. I peeked at the old books as I went through 7Sage for comparison and can't believe that many people carry out their LSAT prep exclusively through their program. If you are serious about your score, it's not worth anyone's time.
Also a point that a lot of people are skipping is that you can accelerate videos when you watch them. 1.4x is optimal for me.
